The castle, located above Landshuts and visible from afar, has only been called "Trausnitz" since the 16th century. Until then, it had the same name as the city itself. According to this, the castle was to grant the country "protection" and protection.
Under Ludwig the Kelheimer, the founder of Burg and Stadt Landshut in 1204 and an important historical figure at the time of the Crusades, the Wittelsbach main castle had grown to the extent of today's core castle. In 1235, when Emperor Friedrich II was visiting Landshut, the castle was essentially completed.
Today the tour takes visitors to the castle through medieval halls such as the impressive vaulted hall of the Alten Dürnitz and the castle chapel with their important sculptural decoration and the winged altars of the rich dukes. Arched cabinets, panelled parlours and the famous stairway with the monumental painted scenes from the Italian Commedia dell'arte represent the era of the Renaissance. The culmination of the castle tour is the view from the Söller on the city.
